The name Hard Knocks in Chinese / Japanese...

挨一拳得一招挨十拳變諸葛 is a Chinese proverb that literally translates as: Receive one blow, [and one] learns a lesson; Receive ten blows, [and one] becomes a great Zhuge [Liang].

You must first understand that a man named Zhuge Liang was one of the great strategists and philosophers in Chinese history. He's known as a man of great wisdom.

Figuratively, this phrase means:
One can learn much from failure or “hard knocks.”

百胜难虑敌三折乃良医 is a Chinese proverb that literally translates as: [Even a general who has won a] hundred victories [may be] hard put to see through the enemy's [strategy], [but one who has] broken [his] arm three [times] [will] be a good doctor.

Figuratively, this means: One cannot always depend on past successes to guarantee future success but one can always learn from lessons drawn from failure.

不磕不碰骨頭不硬 is a Chinese proverb that literally translates as: Without being knocked around a bit, [one's] bones won't become hard.

Figuratively, this means: One can't become strong without first being tempered by “hard knocks.”

While true for everyone, this sounds like the “Iron Body” form of Kung Fu, where practitioners' bodies are beaten (and often bone fractured) in order to become stronger.
For the rest of us, this is just about how we can be tempered and build character through the hardships in our lives.

This is not a common title for a wall scroll in China.

百戦錬磨 is a Japanese proverb or title that means veteran, or rather, someone schooled by adversity in many battles or someone rich in life experience.

If you are who you are because of the adversity you experienced in life, this could be your title.
